researchers have demonstrated that security cameras infected
with malware can receive covert signals and leak sensitive
information from the very same surveillance devices used to
protect facilities.
To transmit sensitive information, the attacker uses the
camera’s infrared light-emitting LEDs, which are typically used
for night vision. The researchers showed how malware can
control the intensity of the infrared to communicate with a
remote attacker that can receive signals with a simple camera
without detection. Then the attacker can record and decode
these signals to leak sensitive information.
